Three-Dimensional Imaging Improves Accuracy in Clip Sizing During Thoracoscopic Left Atrial Appendage Exclusion

Abstract

The AtriClip is an epicardially applied occlusion device for the left atrial appendage. Accurate sizing and placement of the device is essential to its success. We describe the use of 3-dimensional computed tomography imaging to aid in accurate sizing of the AtriClip device during thoracoscopic surgical ablation. This technique reduces the risk of improper sizing of the device and thus mitigates the risk of malpositioning and potential damage or compression to surrounding structures such as the circumflex coronary artery.
